What is Gartner's view of in-line policy enforcement?

"It is important for organizations to establish policies and controls that meet their stated business and regulatory risk-profile. High performance in-line policy monitoring and enforcement on all channels, including messaging increases an organizations security posture by reducing or eliminating incidents of accidental or intentional disclosure."

Why Sentrion MP? All-in-one security without performance degradation

To safeguard brand, reputation and competitive edge, companies must begin establishing a messaging risk-profile that is best suited to their specific policies and business environment. A key influence on the success of an effective messaging initiative is the implementation of technology that enables companies to manage bi-directional messaging policies to protect from growing outside threats - and to prevent inadvertent or intentional leakage of confidential information through outbound messaging without degrading message processing performance.

Why does my business need to DKIM sign email?

To ensure your messages get through an ISP's authentication check to reach recipients, business must start DKIM signing all of their outbound mail.

All major ISPs are adopting email authentication technology-Sender ID, DomainKeys or DomainKeys Identified Mail (DKIM)- These authentication standards are designed to verify that a message from a particular sender is indeed from that sender which helps reduce phishing attacks, spoofing and spam.

These technologies enable ISPs to take actions on incoming e-mail, from throttling to marking e-mail with an "open with caution" notation, to an outright block to protect customers from unwanted or dangerous email from unknown or illegal senders. Although all three standards are reliable, DKIM has an edge over the others.

The emergence of DKIM as an IETF standard and its added protections make it a natural for wide adoption for both the ISPs and corporate enterprises. As the adoption of DKIM accelerates it is extremely important for businesses to begin "digitally signing" their outbound email with DKIM signatures to ensure that their messages are seen as legitimate by ISPs and other corporate enterprises.

With Sentrion DKIM Signer, your business can be up and DKIM signing messages in a matter of hours.

Sentrion Connection Controls

Sentrion Connection Controls provides complete control over inbound and outbound email traffic by throttling trusted email or dropping abusive traffic. It collects broad statistics about the behavior of individual senders, sender reputation, sending hosts, and network address blocks and enforces pre-defined limits. Based on the behavior or reputation of the connection, a range of actions are possible: permanently or temporarily reject; rate limit or throttle; or suspend. This scalable traffic shaping mechanism defends against a variety of attacks and unwanted email, as well as helps to smooth the flow of legitimate traffic.

Proven to eliminate unwanted mail by a minimum of 50%, and with IP reputation application, up to 80% or more

The Sentrion Directory is an LDAP directory that interfaces with existing directories and centralizes users, alternate email addresses, groups, mail distribution lists, administrative groups and policy-related information into a secure and centrally managed data repository. It provides this information to email servers across the enterprise to add intelligence to gateway security, routing, and policy enforcement.
